Latest Patents
Elmar Hartmann holds a patent for a "Method for detecting phase failure in an asynchronous machine." This invention involves monitoring phase currents to identify phase failures effectively. The method generates a trigger signal for each phase when a limit value is undershot. It employs a systematic changeover between different monitoring states to cover the entire frequency range during converter operation. The first monitoring state generates a trigger signal if the instantaneous value of the phase current falls below the limit value. Subsequently, the system transitions to a second monitoring state, where the duration of the trigger signal is compared with the swept angle of rotation of the voltage vector in the same phase. If the phase current state persists during this time, a third monitoring state checks the duration of the trigger signal against a defined delay time interval. If the trigger signal exceeds this interval, a phase failure is signaled.
